3 Claims.

This invention relates to a retaining clip and cap for a pen or pencil.

Hitherto retaining clips which are attached to the pocket of the wearerand have clamping jaws, permit the pen or pencil to become lost byslipping from the jaws.

With the above in mind the present invention has for an object toprovide a pen or pencil cap having a retaining clip releasably locked tothe cap so that a spring dog must be manually released before the capcan be removed from the clip and thus the pen or pencil of which the capis a part, cannot become accidentally lost by slipping from theretaining clip.

A further object is to provide apparatus of this character which will beformed of a few strong, simple and durable parts, which will beinexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists ofcertain novel details of construction and combinations of partshereinafter fully described and claimed, it being understood thatvarious modifications may be resorted to within the scope of theappended claims without departing from the spirit or sacrificing any ofthe advantages of the invention.

In the accompanying drawing forming a part of this specification:

Figure 1 is a longitudinal sectional view of a retaining clip and capconstructed in accordance with the invention, the cap being a part of apen.

Figure 2 is a longitudinal sectional view of the retaining clip and capshowing the dog released to permit the cap being removed from theretaining clip.

Figure 3 is a detail perspective view of the retaining clip and capsupporting ring thereof.

Figure 4 is a perspective view of the push rod for releasing the dog.

Figure5 is a perspective view of the releasable dog.

Referring now to the drawing in which like characters of referencedesignate similar parts in the various views, Ill designates a resilientloop forming the jaw member of the retaining clip, the jaw member beingprovided with corrugations I I adapted to crimp the material of thepocket of the wearer and prevent dislodgement of the clip. A ring I2 issecured to one side of the jaw member by rivets I3 or other connectors.

In accordance with the invention it is proposed to eliminate theconventional cap for a pen or pencil and substitute therefor a. cap [4which may be provided at its open end with screw threads 15 to receive aconventional pen 16 or a pencil may be substituted for the pen, the penbeing herein shown merely for the purpose of an example. The cap I4 istubular, as is conventional, and is closed at the upper end by a plugIT. A flanged button l8 embraces the upper end of the cap and the plug.A push rod l9 of rectangularcross section has one end threadedly engagedas shown at 20 in the button to secure the push rod to the button. Thepush rod is slidably engaged in an axial opening 2| formed in the plugI7, the opening also being of rectangular contour to prevent rotation ofthe push rod. The push rod is of greater length than the plug and isprovided at the lower end with a head 22. The push rod connects thebutton [8 to the cap M for limited upward movement with relation to thecap.

A resilient dog is disposed within the cap [4 and comprises a leafspring shank 23 which is secured by a screw 24 to the plug IT. The leafspring shank is provided at its lower end with a tooth 25 which passesthrough an opening 26 formed in the side of the cap I4 below the ring l2of the retaining clip, see Figure 1. The tooth of the dog prevents thecap I4, of a pen or pencil, from becoming accidentally detached from thering of the clip.

A leaf spring 26 is secured to the lower end of the push rod l9 and isprovided with a longitudinal slot 21 through which the lower end of thedog, carrying the tooth 25, passes. The lower side 28 of the tooth isinclined upwardly and outwardly and the bottom wall of the slot 21 ofthe leaf spring contacts with the lower end of said side of the tooth,see Figure 1.

To release the cap of the pen or pencil from the ring l2 of theretaining clip the button I8 is pulled upwardly with'relation to theclamp M. This upward movement of the button causes the bottom wall ofthe slot 21 to ride up on the inclined side 28 and retract the doginwardly into the cap I to permit the cap being detached from the ringl2 of the retaining clip to eifect removal of a pen or pencil from theclip.

Since the operation of the parts has been described as the descriptionof the parts progressed it is thought the invention will be fullyunderstood without further explanation.

What is claimed is:

1. A cap for a pen or pencil comprising a tubular cap closed at one endand having an open end adapted to receive a pen or pencil, a removablering embracing said cap, a resilient dog within the cap secured at oneend to the closed Within the cap secured at one end to the closed I endof the cap and having a tooth engaged through an opening in the ,capbelow said ring.

to prevent removal of the cap-from"the'ring,"and a push rod slidablyconnected to the cap having a portion engageable with the toothhand-adapted to Withdraw the tooth into the cap; when the,

push rod and cap are movedrelatively 'topermit removal of the cap fromsaid ring.

3. A cap for a pen or pencil comprising a tubular cap closed at one endand having an open end adapted to receive a pen or pencil, a ringembracing said cap, a resilient dog within the cap secured at one end tothe closed end of the cap and having a tooth engaged through an openingin the cap below said ring, a push rod slidably connected to the cap, abutton on the push-rodfor operatingthe pushirod, and a leaflspi'ing'connected to the push rodhaving a longitudinal slot receivingthe tooth, said tooth having an inclined edge engageable with a wall ofsaid slot, said wall riding upon said edge to withdraw ithe'toothinto-the cap when the push rod and 15 cap 'are moved relatively to eachother to permit removal of :the-cap from said ring.
